Week of May 23rd:
A fly and a flea are trapped in a flue.
How far must the fly and the flea fly to flee the flue?
Said the fly to the flea 'to flee is some number times 3.'
Said the flea to the fly 'but 3 squared is too high.'
Responds the fly 'but it'll also do to have some number times 2.'
'Agreed' said the flea. 'Then so it shall be.'
So now it is up to you. How far must the fly and the flea fly to flee the flue?
Answer: 6 units (pick your own)
3 squared is too high, so we know it is less than nine. Since 3 and 2 are factors there is only one number less than 9 with that property.

Week of April 11th:
We start with what a pen can write
Then add an "s" for a tool of lesser might
Change "d" to "n" for an oath professed
Remove letter one for a condition no longer the best
Change "w" to "t" for something forced apart
Reverse my ends, then add an "h" for what's atop a chart
Change "n" to "w" to learn how much an item can fetch
Finally, anagram me for what in baseball may follow a stretch
What did we start with?
What do we end up with?
Answer:
Each line of this riddle is explained as follows:
1. word  We start with  A "pen can write" a word.
2. sword  Then add an "s"  "for a tool of lesser might"  This alludes to the adage: "The pen is mightier than the sword."
3. sworn  Change "d" to "n"  "for an oath professed"
4. worn  Remove letter one  "for a condition no longer the best"  If something is worn, then its condition has deteriorated.
5. torn  Change "w" to "t"  "for something forced apart"
6. north  Reverse my ends, then add an "h"  "for what's atop a chart"  Switch the first and last letters of "torn" giving "nort", then add an "h" giving "north". "North" (or "N" representing "North") is usually found at the top of a chart.
7. worth  Change "n" to "w"  "to learn how much an item can fetch"  The worth, or value, of something will determine how much money it can get in exchange for it.
8. throw  Finally, anagram me  "for what in baseball may follow a stretch"  "Throw" is an anagram of "worth". In baseball, the pitcher may throw the ball after a certain windup known as a stretch.

Answer:
29 rungs
The firefighter is standing on the middle rung. He climbs up 6 rungs, so he is now at Middle+6. He then goes down 10 rungs, so he is now at Middle4. He goes up 18 rungs, so he is now at Middle+14=Top. 14 rungs from the top, 14 rungs from the bottom and the middle rung. 14+14+1=29!

Four people arrive at a river with a narrow bridge that can only hold two people at a time. It’s nighttime and they have one torch that must be used when crossing the bridge. Person A can cross the bridge in one minute, B in two minutes, C in five minutes, and D in eight minutes. When two people cross the bridge together, they must move at the slower person’s pace. Can they all get across the bridge in 15 minutes or less?
Answer: Yes, they can cross in exactly 15 minutes. The group of four must follow these three steps.

First, A and B cross the bridge and A brings the light back. This takes 3 minutes.

Next, C and D cross and B brings the light back. This takes another 10 minutes.

Finally, A and B cross again. This takes another 2 minutes.
